There are a series of spacers on the right side rear set of my Monster. I'm sure they are there on every similar Monster. They are not on the left side. Why are they there? It doesn't seem to be a clearance issue. My best guess is they're there because of the smog canister. I have removed my canister. I want to get rid of those spacers so it is symmetrical with the other side and I have more access to the rear brake lever. But I figure I better ask before I go ahead with it.
